Abstract
Potential human health effects of material emissions in new car cabins are of great public concern. In present work, four new cars with different equipment were tested to assess the nature of volatile organic compounds (VOCs) associated with new vehicle interior. Air samples were collected on solid sorbents and analyzed using thermal desorption and GCMS/ FID. Different types of sorbents were applied to effectively adsorb VOCs. The maximal number of VOCs, trapped from the in-vehicle air, was identified and compounds occurring in air from cabins of all examined vehicles were selected and classified. VOCs emission from identified compounds was calculated and potential sources of identified VOCs were discussed. For aromatic hydrocarbons, the comparison of individual VOCs concentrations was performed.
Highlights
In recent years, greatly increased attention has been focused on the quality of indoor air
According to the World Health Organization (WHO) [1], organic indoor pollutants, sampled by adsorption onto solid sorbents, have been classified into four groups concerning their boiling-point ranges: very volatile organic compounds (VVOC) with a boiling point range from 0 oC to 50 – 100 oC, volatile organic compounds (VOC): 50 – 100 oC to 240 – 260 oC, semivolatile organic compounds (SVOC): 240 – 260 oC to 380 – 400 oC and organic compounds associated with particulate matter or particulate organic matter (POM): > 380 oC

Summary
Greatly increased attention has been focused on the quality of indoor air. Airborne pollutants in new car cabins are responsible for a “new car odor”. To many, this odor is considered to be pleasant, but to some car users may be a strong nuisance and at high concentration may evoke sensory irritation. According to the World Health Organization (WHO) [1], organic indoor pollutants, sampled by adsorption onto solid sorbents, have been classified into four groups concerning their boiling-point ranges: very volatile organic compounds (VVOC) with a boiling point range from 0 oC to 50 – 100 oC, volatile organic compounds (VOC): 50 – 100 oC to 240 – 260 oC, semivolatile organic compounds (SVOC): 240 – 260 oC to 380 – 400 oC and organic compounds associated with particulate matter or particulate organic matter (POM): > 380 oC.
